Detecting broken pipe in Solaris send() call

Question

In solaris how to detect broken socket in send() call? i dont want to use signal.
i tried SO_NOSIGPIPE and MSG_NOSIGNAL but both are not available in Solaris and my program is getting killed with "broken pipe" error.

Is there any way to detect broken pipe?

Thanks!

Answer 1

You'll have to use sigaction() to specifically ignore the SIGPIPE signal:

struct sigaction act;

act.sa_handler = SIG_IGN;
sigaction(SIGPIPE, &act, NULL);

...then send() will return -1 with errno set to EPIPE.

Answer 2

I guess in Solaris you have only limited options. AFAIK, sigaction suggested by caf appears to be the best solution.
